Final answer:
The supravesical, paravesical, and pararectal fossa are anatomical spaces within the male pelvic cavity, adjacent to the bladder and the rectum.
Step-by-step explanation:
The supravesical fossa, paravesical fossa, and pararectal fossa are all anatomical spaces found within the pelvic cavity. These fossae are related to the bladder and rectal areas in the pelvic region. The correct answer to where and in what sex these spaces are found is A) Male, within the pelvic cavity. The supravesical fossa lies above the bladder, the paravesical fossa is adjacent to the bladder laterally, and the pararectal fossa is located next to the rectum. The female pelvis, in comparison, is wider and constructed to accommodate childbirth, but the specific fossae mentioned are most commonly referenced within the male anatomy.
